 ==== Storage ====
-Shared scratch storage is being planned, but not yet available. Techstaff hopes to have this done in time for the winter quarter.
+There is slow scratch space mounted to ''%%/scratch%%''. It is a ZFS pool consisting of 10x 2TB 7200RPM SAS drives connected via a LSI 9211-8i and is made up of 5 mirrored VDEVs, which is similar to a RAID10. The servers uplink is 1G ethernet.
+  * Files older than 90 days will be deleted automatically.
+  * Scratch space is shared by all users.
 ==== Utilization Dashboard ====
 Sometimes it is useful to see how much of the cluster is utilized. You can do that via the following URL: http://peanut.cs.uchicago.edu
 ==== Partitions / Queues ====
+To find out what partitions we offer, checkout the [[techstaff:slurm#sinfo|sinfo]] command.
 As of December, 2015 we have will have at least 2 partitions in our cluster; 'debug' and 'general'. An other partition is not guarenteed and will server a specific purpose.

 | **debug** | The partition your job will be submitted to if none is specified. The purpose of this partition is to make sure your code is running as it should before submitting a long running job to the general queue. |
 | **general** | All jobs that have been thoroughly tested can be submitted here. This partition will have access to more nodes and will process most of the jobs. If you need to use the ''%%--exclusive%%'' flag it should be done here.|
-| **hardware** | The purpose of this partition is to set aside nodes that do not use the virtualization layer. This is important if you need true hardware access. |
